Electron-Catalyzed Fluoroalkylation of Vinyl Azides.

The transition-metal free fluoroalkylation of vinyl azides is herein reported. This operationally simple reaction employs the Togni reagent as a CF3 source, Bu4 NI as an initiator, and occurs under electron catalysis. A range of readily prepared starting materials are functionalized using this approach to produce both phenanthridines and quinoxalin-2-ones.
